[PATCH] futex: remove unneeded barrier
When disassembling a kernel I found around over 90 sync Instructions from mb, rmb and wmb calls in the kernel and only few of those make any sense to me. So here's the first one - I think the wmb() in kernel/futex.c is not needed on uniprocessors so should become an smb_wmb().
